I've been pleased with Pet Food Warehouse, which has a frequent buyer card
for their super premium mix (really good stuff - very little waste!) and has a
good assortment year round. (Their supplier had a problem with some sort of
insect in the feed last year, and PFW had very limited quantities for a few
months. However, I've bought there for many years and this was the first such
occurrence.) I also like Guy's Farm and Yard, near Taft Corners. The people are
helpful, they've got the best assortment of feeders I've found anywhere, and
drive-through is a great idea.
